Embodiment Construction

[0039] The present invention will be further elaborated below in conjunction with embodiment.

[0040] The present invention is aimed at the difficulty of closing the technical scheme of reusable aerospace aircraft with two levels of take-off and landing into orbit, and proposes a new aerodynamic layout and corresponding horizontal parallel mode, which satisfies the TBCC-based TSTO flight principle and achieves full-speed domain, Design requirements such as lift-drag matching, push-drag matching, maneuverability matching, and bulk-weight matching in the entire airspace have realized the closure of the TSTO technical solution in the conceptual design stage.

[0041] Such as figure 1 As shown, the layout of the aerospace plane proposed by the present invention is composed of two-stage aircraft connected horizontally up and down. The lower first-stage aircraft adopts liquid hydrocarbon fuel TBCC combined power propulsion, carries the upper second-level aircraft on its back and t...

Abstract

The invention relates to a horizontal taking-off and landing two stage to orbit (TSTO) reuse aerospace plane layout. A first-stage aircraft and a second-stage aircraft are included, and the second-stage aircraft and the first-stage aircraft are in up-down horizontal parallel layout; the second-stage aircraft is in wing body combination body layout with a wedge-shaped head, a fusion edge strip, a small-span-chord-ratio sweepback thin wing and a central vertical fin; and the first-stage aircraft is in wing body combination body layout of a cathedral sweepback wing with the waverider characteristic, a downwards-folding wing tip and a V tail. The horizontal taking-off and landing TSTO reuse aerospace plane layout meets the TSTO flight principle based on the turbine based combined cycle (TBCC),the design demands of the whole speed domain, the whole airspace lift-drag matching, push-resistance matching, operation-stability matching, volume-weight matching and the like are reached, and the closure of the TSTO technical scheme in the conceptual design stage is achieved.

Description

technical field [0001] The invention belongs to the technical field of hypersonic aircraft, and relates to the aerodynamic layout form of a horizontal take-off and landing two-stage reusable aerospace aircraft. Background technique [0002] Aerospace planes are the product of a high degree of integration of aviation and aerospace technologies. Realizing rapid and repeatable space-to-ground round trips can greatly reduce launch costs, greatly reduce launch cycles, and greatly improve aerospace applications. The aerospace plane is the ultimate development goal of aerospace technology. Since the German scientist Sanger first proposed the concept of the aerospace plane in 1935, the international aerospace powers represented by the United States have successively launched a number of aerospace plane concepts, including rocket-powered / Air-breathing power and combined power schemes, single-stage / multi-stage orbiting schemes, horizontal / vertical launching and landing schemes, etc. ...
